I found this slide presentation is very useful. Great Job ! This Slide Presentation is very nice. Easy to understand ’ current event and understands ’. Our regular update blog news visit http://archaeologyexcavations.blogspot.com

‘everyday’ projects?
the design research projects you hear about most often are
enormous, time consuming and expensive.
most projects we work on can’t bear that.
research can/should be customised to
suit the project requirements

7.
what we’ll cover
PART ONE: Designing Design Research
PART TWO: Conducting Design Research
PART THREE: Analysing Design Research
LOTS of hands on exercises.
Lots of your questions & shared experiences
Focus on QUALITATIVE Research
(esp. interview format)
Focus more on practical ‘what you can actually
do’ than ‘best practice’

17.
mathematics and natural sciences
Quantitative
statistically sound, scientific
large random samples
questionnaires, surveys, tests
Quantitative research is the systematic scientific
investigation of quantitative properties and
phenomena and their relationships. The objective
of quantitative research is to develop and employ
mathematical models, theories and/or hypotheses
pertaining to natural phenomena. The process of
measurement is central to quantitative research
because it provides the fundamental connection
between empirical observation and mathematical
expression of quantitative relationships.

18.
social sciences
insight gathering, exploratory
small sample sizes
Qualitative participatory, observational,
interviews, analysis of
documents & materials.
Qualitative research ...aim(s) to gather an in-depth
understanding of human behavior and the reasons that
govern human behavior. Qualitative research relies on
reasons behind various aspects of behavior.
Simply put, it investigates the why and how of decision
making, not just what, where, and when.

19.
‘To design an easy-to-use
interface, pay attention to what
users do, not what they say.
Self-reported claims are
unreliable, as are user
speculations about future
behaviour.’
- jakob nielson

20.
choose qualitative for insight
but ideally, combine quantitative
and qualitative inputs
quantitative can be great for problem
identification & solution validation

23.
understanding the problem:
what are you trying to learn?
- the problem is not always
what it first appears to be
- define your research questions
- what might be the best ways
to answer those questions?

24.
understanding the problem:
what is the context for the
problem?
- care not to narrow the context early
- are their multiple relevant contexts?
- WHERE can we learn about the people’s behaviour
in relation to this problem?
- research as close to context as possible.

28.
EXERCISE! Part 1
Your client is a grocery store.
They want you to do some research and make
recommendations about how they can provide a
better online grocery shopping experience for
their customers.
You have unlimited time & budget
for your research.
What research activities would you suggest?

36.
how many?
as few as possible.
if given the choice to more research
studies with few participants.
why?
- diminishing returns
- speed to action (design)

37.
(yes, I’m quoting Jakob again - Why you only need to test with 5 users)
In earlier research, Tom Landauer and I [Jakob Nielsen]
showed that the number of usability problems found in a
usability test with n users is:
N(1-(1-L)n)
where N is the total number of usability problems in the
design and L is the proportion of usability problems
discovered while testing a single user. The typical value of L
is 31%, averaged across a large number of projects we
studied. Plotting the curve for L=31% gives the following
result:

38.
The most striking truth of the curve
is that zero users give zero insights.

39.
how to find them?
DIY vs Using Professionals
- how much time/money do you have?
- how easily accessible are participants?
is using friends/family network really bad?

44.
discussion guide
> define your research questions
> start as wide as possible, narrow slowly
> keep it contextual, not speculative
> show, don’t tell (observation = good)
(show me how you do that?)
> uncover mental models
(if you clicked there, what do you think would happen?)
> ask OPEN questions
(ask questions to get them talking NOT yes/no answers)
> take care not to lead
(you can have leading questions AND leading structures)
> don’t outsource design to your participant!
(remember, you’re the designer!)

48.
what to capture on
sticky notes
> *anything* interesting/relevant said in the
course of your interview, in as close to direct
quotes as possible.
> your design ideas
> questions for the future
> capturing on the fly is a *real* skill. I still live
transcribe to a text file then extract affinity
notes from the transcription.

49.
interview technique
introductions & getting started
- introduce yourself (and any colleagues)
- what are we doing here?
- what time will we finish
- forms & incentives
- ask permission to record

50.
interview technique
it’s not a test!
- allay their nerves
- distance yourself from the design
- we only care about *their* opinion, not people
they know or ‘most people’
- there’s no right answer or smart answer
- their opinion counts - will really help shape the
design of the product/service

51.
interview technique
building rapport
*everyone* has something that makes them
either very interesting or passionate.
find it. talk about it.
the investment in building rapport is repaid by
the quality/quantity of insight given.

53.
interview technique
Have a great closing question.
Some of my favourites are:
- Do you know someone you might
recommend this to? Who/Why
- How would you rate it out of 10
- What would you tell the designers
Try to summarise the parting sentiment
(notes that it is not more or less important than the initial sentiment)

66.
using research data in design:
audience modelling
Today I’m pissed
HI at British Gas
I’m passionate
about Education
Proximity
am I experiencing once my billing the more I learn
‘it’ right now? problem is fixed, the more I care
I’m fine.
LOW HI
Commitment
how much will I care next month?

Keith ‘I just want to know enough to buy well’
Keith is planning to pop the question soon - in about a weeks time
The engagement ring will be his first big jewellery purchase.
He knows virtually nothing about diamonds or jewellery. He doesn’t want to become
and expert, he just wants to know enough to buy well and wants to feel reassured
using research data in that he’s getting what he’s paying for.
He has a general idea of his girlfriend’s preferred style but is not really confident
about choosing the right design. Some of his mates have been engaged recently and
models: personas
he’s asked them a few questions about the process.
He popped into Goldsmiths last week to tentatively start investigating his purchase
